IMPROVEMENT IN SUCKER-ROD SOCKETS FOR OIL AND OTHER WELLS..

Specication forming part of Letters Patent No. 212,831, dated March 4,1879; application led May 1o, 187e.

To all whom it may concern.'

Be it known that I, JOHN H. BAIE, of Parker Oity, county of Armstrong,and State of Pennsylvania, have invented a new and useful Improvement inSucker-Rod Sockets for Oil or Salt Wells, which improvement is fully setforth in the following specification, reference being' had to theaccompanying drawings, wherein- Figure l is a plan view oi1 thevalve-socket. Fig. 2 is a central vertical section.

I'he object of' my invention relates to the construction ot' a devicefor raising suckerrods ont ot' oil or salt wells when they have parted,leaving` a portion of the sucker-rods in the tubing in the well, oftencausing great delay in raising it, and in some cases requiring the tubinto be drawn, thereby incurring expense and the risk ot' dropping thetool in the tubing in the well.

The socket A, Fig. Il, is made of a piece of iron pipe to iit the insideof the tubing, having a screw head and thread, B, at one end, and anopening', M, at the other end, with its edges beveled inwardly, so as todirect the sucker-rod or drill or the tools to be drawn, in-

4to the mouth or opening M. The socket A is long enough to allow itspassage down around the sucker-rods, so as to secure a iirxn hold. Thesocket A has two openings opposite each other, in the lower end of eachof which a valve or catch, O, is placed, having its upper end sharpened,the lower end being lirmly secured to the socket A by a hinge, IL, orother device, so that the lower end of the valve or catch G will tit onthe lower part of the opening O in the socket A. These valves or catchesO are inclined toward the inside ofthe socket A, and are held in thisposition by springs S,

the sucker-rods 1n an oil or fastened on the outside of the socket A,when salt well part, leaving a portion in the tubing in the well. Thesocket A is screwed into the end of a sucker-rod by means of the screwB, and is lowered into the well. IVhen the socket A reaches the rods iuthe tubing in the well it passes down over them, the valves or catches Oare forced back, the rod passes up into the socket A, the springs Sforce the valves or catches O inwardly, and, by raising on the socket A,the catches O, pressing into the wood or iron of the sucker-rod, take arm hold and draw it out.

It will be observed that in Iny construction the tools or materials tohe drawn up by my device may be as lai-ge in cross-section as thecross-section of the opening m in the pipe A, and that the parts to bedrawn up will press, if sufficiently large, the hinged catches C outward in the slots, so that they will be in the line ot' the bore of thepipe.

I am aware that a tool-extractor or drillrod grab consisting ofatube-section provided with a single catch has heretofore been employed,and I therefore lay no claim to such invention.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is-

The socket A, provided with slots o o, beveled edge m, and screw-head B,in combination with the catches O, hinged in the lower ends of theslots, and springs S, substantially as described, and for the purposeset forth.
